, HOOP FOR BARRELS, &.o.

SPECIFICATION forming part of Letters Patent No. 523,281, dated July1'7, 1894. Application filed October 19, 1893- Serial No. 488,601. (Nomodel.)

.To all whom it may concern.-

Be it known that'I, HENRY S. Horrna, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented new and'useful Improvements in Hoops for Barrels, Wooden Ware,

and Oooperage Generally, of which the following is a specification.

My invention relates to metallic hoops for to barrels, woodenware andcooperage'generally,

but more particularly to the chine or end hoops for barrels.

The object of my invention, is to provide a hoop of proper shape to notonly hold the r 5 ends of the staves together against or'around the headof the barrel, but also to provide a support and protection to theendsof the staves which project beyond the head, thereby preventing themfrom being broken down in ac ending up the barrel, or in chining same,2'. e.,

in rolling upon the edge.

It consists essentially in a hoop having a rounded projection or bead,formed in one edge and extending the whole length of the 2 5 hoop andentirely around the barrel at the end of the staves as will be moreparticularly described in the following specification and claims.

In the drawings Figure 1, is a perspective view of a hoop embodying myinvention.

Fig. 2, is a full size sectional view of a portion of a barrel, showingsection of hoop of preferred form as applied. Fig. 3, is a view of abarrel provided with chine hoops em- 5 bodying my invention. Fig. 4, isa sectio of another form of a'hoopu In Fig. 2, A is the end of a stave.B is a portion of the head, and G a section of the hoop in place. I r

In forming the .croze to hold the heads of barrels and the bottoms ofpails and tubs, a considerable portion of the staves is cut away,thereby weakening them at a most critical point. This weakness is mostnoticeable in flour and other stack barrels,which are usually made ofvery light thin materialand in the process of ending them up, and inrolling them upon the chine, the whole weight of the barrel and contentsis thrown upon the pro weakened by cutting the croze, are too light towithstand the strain, and break 0d at the croze, thereby releasing thehead.

As will be seen in Fig. 2, I propose to first turn the edge of the hoopoutward and then inwardly again until it comes in line with the fiatpart of the hoop, thereby forming a projecting ridge or bead upon oneedge having curved surfaces both crosswise of the hoop, and alsolengthwise of it. This prac- 8o tically double arched form makes theotherwise flexible hoop very rigid and forms a solid support upon whichto roll or chine the barrel without causing undue strain 'upon theprojecting ends of the staves. In practice this form is'given to thehoop which is preferably of a uniform thickness at the same time it issplayed or rolled to give it the proper taper to fit the barrel, therolls for that purpose being formed so as to shape one edge as describedwhile the opposite edge is stretched to give the hoop the necessarytaper, though it'would come clearly within the scope of my invention toform the hoop as described by pressing it between dies or otherwise. 7 5

The raw or sharp edge .of the hoop being turned inwardly against the endof the staves, only smooth curved surfaces come in contact with thefloor, in rolling upon the chine. Consequently barrels or tubs providedwith this hoop do not damage the floors and benches as does ware havingthe ordinary iron hoops.

It will also be noticed in Fig. 2, that this form of hoop, can be drivenon farther in case the ware shrinks as with ordinary hoops, for the edgeof the hoop turned inwardly comes just in line with the flat part of thehoop.

While I prefer to form this hoop from metal strips of a uniformthickness throughout, as it go is usually found in commerce, it may alsobe formed in the process of manufacturing the metal strips of thesection shown in Fig. 4, 71.6., with a solid projecting ridge or beadupon one edge and a perfectly flat inner surface.

In Figs. 1 and 3, I show the ends of the hoop joined by rivets which isat the present time the most practical, 'mode of securing jectiug endsof the staves, which already 50 them. However, they may be welded orotherwise united without departing from the scope of my invention.

What I claim as new, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, a metallic hoop for barrelsconsisting of a flat metallic strip having a continuous roundedprojeotion or ridge formed in one edge, substantially as and for thepurpose described.

2. As a new article of manufacture, a hoop for barrels consisting of aflat metallic strip of uniform thickness throughout and having acontinuous rounded projection or corrugation bent in one edge, wherebyit is stiffened transversely and the ends of the staves are protected,substantially as described.

3. As a new article of manufacture, a metallic hoop for barrelsconsisting of a flat merounded surfaces to come in contact with exteriorobjects, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
